A144 kg park bench made of iron sits on the sun, its temperature increases from 25c to 35c, how many kilojoules of energy does the bench absord?

Mass of the iron bench = 144 kg

The iron will absorb energy from the sun and its temperature will increase from 25 degree Celsius to 35 degree Celsius

Change in the temperature = 35 - 25 = 10 degree Celsius

Specific heat capacity of the iron (c) = 460.54 J/Kg C

Heat gained by the iron bench = M × c × ΔT

Heat gained by the iron bench = 144 × 460.54 × 10

Heat absorbed = 663177.6 Joules

Hence, to raise the temperature from 25 to 35 degree Celsius, the iron bench will absorb energy from the sum = 663177.6 Joules
